Treatment schedule:
The treatment schedule should be based on veterinary diagnosis, the local epidemiological situation and/or the epidemiological situation of other areas the dog has visited or is going to visit. If based on veterinarian opinion re-administration(s) of the product is required, any subsequent administration(s) must follow the minimum 1 month interval schedule.
The product should only be used in dogs when treatment of ticks / fleas / mites and gastrointestinal nematodes is indicated at the same time. In the absence of the risk of mixed co-infestation, a narrower spectrum parasiticide should be used.
Treatment of flea and tick infestations and gastrointestinal nematodes:
The veterinary medicinal product can be used as part of the seasonal treatment of fleas and ticks (replacing treatment with a mono-active flea and tick product) in dogs with diagnosed concurrent gastrointestinal nematode infections. A single treatment is efficacious for the treatment of gastrointestinal nematodes. After treatment of the nematode infections, further flea and tick treatment should be continued with a mono-active product.
Prevention of heartworm disease and angiostrongylosis:
A single administration also prevents lungworm disease (by reducing the immature adults (L5) of A. vasorum) and heartworm disease (D. immitis) for one month. When the product replaces another lungworm or heartworm preventive product, the first dose of the product should be given within a month of the last dose of the former veterinary medicinal product. In endemic areas, dogs should receive lungworm and/or heartworm preventive treatments at monthly intervals. It is recommended that heartworm prevention treatment should be continued until at least 1 month after the last exposure to mosquitoes.
Prevention of establishment of thelaziosis (adult Thelazia callipaeda eyeworm infection):
Monthly administration of the product prevents establishment of infection with adult Thelazia callipaeda eyeworm.
Treatment of demodicosis (caused by Demodex canis):
Administration of a single dose once monthly for two consecutive months is efficacious and leads to a marked improvement of clinical signs. Treatment should be continued until skin scrapings are negative on at least two consecutive occasions one month apart. As demodicosis is a multifactorial disease, it is advisable to also treat any contributing, underlying conditions appropriately.
Treatment of sarcoptic mange (caused by Sarcoptes scabiei var. canis):
Administration of a single dose at monthly intervals for two consecutive months. Further monthly administrations of the product may be required based on clinical assessment and skin scrapings.
Contra-indications, warnings, etc
Do not use in cases of hypersensitivity to the active substances or to any of the excipients.
Ticks and fleas need to start feeding on the host to become exposed to sarolaner; therefore, the transmission of infectious parasite-borne diseases cannot be excluded.
This veterinary medicinal product is not effective against adult D. immitis. However, accidental administration to dogs infected with adult heartworms should not pose safety concerns. Dogs in areas endemic for heartworm (or those which have travelled to endemic areas) may be infected with adult heartworms. Maintenance of the efficacy of macrocyclic lactones is critical for Dirofilaria immitis control. To minimise the risk of resistance selection, it is recommended that dogs should be checked for both circulating antigens and blood microfilariae at the beginning of each season of preventative treatment. Only negative animals should be treated.
Parasite resistance to any particular class of parasiticides may develop following the frequent, repeated use of a product of that class. Therefore, the use of this product should be based on the assessment of each individual case and on local epidemiological information about the current susceptibility of the target species in order to limit the possibility of a future selection for resistance.
In the absence of available data, treatment of puppies less than 8 weeks of age and/or dogs less than 1.25 kg bodyweight should be based on a benefit-risk assessment by the responsible veterinarian.
The product was well tolerated in dogs with a deficient multidrug-resistance-protein 1 (MDR1 -/-). However, in such sensitive breeds (which may include, but not necessarily limited to, Collies and related breeds), the recommended dose should be strictly observed.
The safety of the veterinary medicinal product has not been established during pregnancy and lactation or in dogs intended for breeding. The use in these animals is not recommended.
Very rare
(<1 animal / 10,000 animals treated, including isolated reports):
Gastrointestinal signs (such as vomiting, diarrhoea)1
Systemic disorders (such as lethargy, anorexia)1
Neurological signs (such as tremor, ataxia, convulsions)2
1In most cases these signs are mild and transient.
2In most cases these signs are transient.
Reporting adverse events is important. It allows continuous safety monitoring of a veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to either the marketing authorisation holder or its local representative or the national competent authority via the national reporting system. See also section "Contact details" of the package leaflet.
User warnings:
Wash hands after handling the product.
The accidental ingestion of the product may potentially result in adverse effects, such as transient excitatory neurological signs. To prevent children from accessing the product, only one chewable tablet at a time should be removed from the blister pack and only when required. The blister pack should then be returned into the carton immediately after use and the carton should be stored out of the sight and reach of children. In case of accidental ingestion, seek medical advice immediately and show the package leaflet or the label to the physician.

Further information
Ticks on the animal prior to administration or from new infestations after product administration are killed within 48 hours. For the species I. ricinus, this onset of efficacy is within 24 hours, during the 35-day period after product administration.
For fleas, the onset of efficacy is within 12 to 24 hours of attachment for five weeks after product administration. Fleas on the animal prior to administration are killed within 8 hours. The veterinary medicinal product kills newly emerged fleas on the dog before they can lay eggs and therefore it prevents environmental flea contamination in areas to which the dog has access.
Sarolaner is an acaricide and insecticide belonging to the isoxazoline family. The primary target of action of sarolaner in insects and acarines is functional blockade of ligand-gated chloride channels (GABA-receptors and glutamate-receptors). Sarolaner blocks GABA- and glutamate-gated chloride channels in the central nervous system of insects and acarines. Sarolaner is active against adult fleas (Ctenocephalides felis and Ctenocephalides canis) as well as several tick species such as Dermacentor reticulatus, Ixodes hexagonus, Ixodes ricinus and Rhipicephalus sanguineus, as well as the mites Demodex canis and Sarcoptes scabiei var. canis.
Moxidectin is a second generation macrocyclic lactone of the milbemycin family. Its principal mode of action is interfering with neuromuscular transmission at the level of the glutamate-gated chloride channels and, to a lesser extent, of GABA (gamma amino butyric acid)-gated channels. This interference leads to the opening of the chloride channels on the postsynaptic junction to allow the inflow of chloride ions. This results in flaccid paralysis and eventual death of parasites exposed to the drug. Moxidectin is active against adults of Toxocara canis, L4 larvae and immature stages (L5) of Ancylostoma caninum, L4 of Dirofilaria immitis and immature stages (L5) of Angiostrongylus vasorum and Thelazia callipaeda.
Pyrantel is a nicotinic acetylcholine (ACh) channel receptor (nAChR) agonist. Pyrantel mimics the agonist effects of ACh through high affinity binding to subtype specific ionophoric nAChRs in nematodes, while not binding at muscarinic mAChRs. Following receptor binding, the channel opens to allow the influx of cations resulting in a depolarization and excitatory effects on nematode muscle, ultimately leading to spastic paralysis of the worm and death. Pyrantel is active against immature stages (L5) and adults of Toxocara canis, adults of Ancylostoma caninum, Toxascaris leonina and Uncinaria stenocephala.
In this fixed combination, moxidectin and pyrantel provide complementary anthelmintic efficacy through distinct mechanisms of action. In particular, both active substances contribute to the overall efficacy against the gastrointestinal nematodes Ancylostoma caninum and Toxocara canis.
No adverse reactions were observed in 8-weeks old healthy puppies administered with up to 5 times the maximum recommended dose for 7 consecutive monthly administrations.
In a laboratory study, the product was well tolerated in dogs with a deficient multidrug-resistance-protein 1 (MDR1 -/-) following single oral administration at 3 times the recommended dose. After a single administration of 5 times the maximum recommended dose to this sensitive dog breed, transient ataxia and/or muscle fasciculation were observed.
Macrocyclic lactones including moxidectin have been shown to be substrates for p-glycoprotein. Therefore, during treatment with the veterinary medicinal product, other products that can inhibit p-glycoprotein (e.g. cyclosporine, ketoconazole, spinosad, verapamil) should only be used concomitantly according to the benefit-risk assessment of the responsible veterinarian.
